JAR-WRENCH.

Specification of Letters Patent.

Patented Jan. 7, 1908.

Application tiled July l2. 1907. Serial No. 383,467.

To all whom 'it may concern:

Be it known that I, EDWIN F. IvEs, a citizen of the United States, residing at Wallingford, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Jar-l/Vrenehes; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1 a top or plan view of a jar wrench constructed in accordance with my invention showing a device adapted to remove either metal or glass caps. Fig. 2 a side view of the outer end of the same. Fig. 3 a reverse plan view of the wrench. Fig. 4 a plan view of the outer end of the wrench, having two pairs of gripping jaws. Fig. 5'a side view of the same. Fig. 6 a longitudinal sectional view of the same. Fig. 7 a plan view of one of the plates showing the form before the teeth thereon are turned. Fig. S a perspective view of the detached jaw illustrating a modified form of gripping surfaces. This invention relates to an improvement in jar wrenches, that is, a device for removing or applying tops to fruit jars, and is an improvement on the jar opener shown and described in my application filed April 15, 1907, Serial No. 368,146, the object of this invention being to so arrange the jaws that one will move the other; and the invention consists in the construction hereinafter described and particularly recited in the claims. In carrying out my invention, I employ a handle 2 having a head 3. In the head 3 I preferably form a clearance opening 4 for the central hub frequently found in jar tops. Secured to the head 3 by rivets 5 and 6 in line with the longitudinal axis of the handle 2 are plates 7 and S formed respectively with outwardly extending ends 9 and 10, these ends projecting at opposite sides of the head. The plates are also formed with flat bearing faces 11 and 12 and with lingers 13 and 14 which bear thereon, the faces 11 and 12 being arranged in parallel planes so that when one plate is turned the other is moved to correspond.

Preferably and as shown in the drawings, a pair of lates will be secured to each side of the han e, and the ends 9 and 10 of the plates 7 and 8 may be formed with a series of teeth 15 which are turned at right angles to the plate and arranged tangentially so as to present a series of sharp gripping edges 16 to grip a metal cap; or they may have ydownwardly and inwardly rejecting fingers 17 and 18 like the fingers s iown in my previous application for removing glass tops from fruit jars, the fingers being forced between the cap and the jar, or, if desired, a set of plates corresponding to the plates 7 and 8 may be secured to each face of the head as shown in Figs. 5 and 6 of the drawings. I/Vith two pairs of jaws as thus arranged, t e cap can be turned either on or ofi' the jar. Instead of forming the plate with the teeth 15 they may be formed with segmental flanges 19 as shown in Fig. S of the drawings; and so formed the inner face of the flange will be serrated or roughened so as to grip the metal cap. Ineither form it will be seen that the movement of either jaw in either direction moves the other jaw, so that when applied to the cap the two jaws will firmly grip them.

I claim 1. In a jar wrench the combination with the handle and head thereof, of a pair of plates pivoted thereto each plateformed with ends, and each plate formed with a finger posite sides of the pivots, substantially as described.

2. A jar wrench `comprising a handle, a head at one end thereof, plates pivoted to said head in line with the longitudinal axis of said handle, said plates formed with outwardly extending jaws and with bearing faces at one side of the pivots, and each plate formed with a finger on the opposite side of the pivots adapted to bear upon the said face of the other plate, substantially as described.

3. The herein described jarwrench comprising a handle, a pair of plates pivoted to each side of the one end thereof, said plates each formed with jaws and each with a bearing face, and each with an inwardly extending finger adapted to bear upon the face of the other plate whereby the movement of either jaw will positively move the other jaw, substantially as described.

4. The herein described jar wrench, comprising a handle, plates pivoted to the outer end thereof in line with the longitudinal axis of the handle, said plates formed with out- In testimony whereof7 I have signed this Wardly extending ends, With bearing faces specification in thepresence Oftwo subseribl0 and ach with a ingfler adalpted tl bear upln ing Witnesses.
